首先采用直流电化学沉积法，在氧化铝模板内成功合成了 Pt/Ni 异质纳米线的有序阵列，并通过X射线衍射仪(XRD)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)对所合成样品的晶体结构和形貌进行了表征测试。然后将Pt/Ni异质纳米线修饰在玻碳电极上，利用循环伏安法和计时电流法对比研究了这种新型纳米结构对甲醇的电催化性能，结果表明， Pt/Ni异质纳米线具有明显优于 Pt 或 Ni 纯金属纳米线的甲醇催化活性和稳定性。

Pt/Ni heterostructure nanowires were fabricated by electrochemical deposition method with the help of anodic aluminum oxide (AAO)template.The morphology and structure of the nanowires were characterized by X-ray diffraction,scanning electron microscopy and transmission electron microscopy.Then,the composite of Pt/Ni nanowires and nafion were employed to modify a GC electrode.The activity and stability of this electrode to the methanol oxidation were evaluated by cyclic voltammetry and chronoamperograms methods.The results indicated that Pt/Ni heterostructure nanowires were a promising new class of catalyst for methanol oxidation and for direct methanol fuel cell applications.
